Ion Java StackOverflow vulnerability
Impact
A potential denial-of-service issue exists in ion-java for applications that use ion-java to:
- Deserialize Ion text encoded data, or
- Deserialize Ion text or binary encoded data into the
IonValuemodel and then invoke certainIonValuemethods on that in-memory representation.
An actor could craft Ion data that, when loaded by the affected application and/or processed using the IonValue model, results in a StackOverflowError originating from the ion-java library.
Impacted versions: <1.10.5
Patches
The patch is included in ion-java >= 1.10.5.
Workarounds
Do not load data which originated from an untrusted source or that could have been tampered with. Only load data you trust.
If you have any questions or comments about this advisory, we ask that you contact AWS/Amazon Security via our vulnerability reporting page [1] or directly via email to aws-security@amazon.com. Please do not create a public GitHub issue.
